CAR-TRUCK FRAM E SPECIFICATION forming part of Letters PatentNo,.461,413, dated October 20, 1891.

Application filed May 16, 1891. Serial No. 392,975. (No model.)

To all whom/it may concern.-

Be it known that 1, DAVID L. BARNES, of Chicago, Cook county, State ofIllinois, have invented a new and useful Improvement in Truck-Fran1es,of which the following is a full, true, and exact description, referencebeing had to the accompanying drawings.

This invention relates to an improvement in truck-frames, and especiallyof the kind designed for passenger-vehicles, though it is not limitedthereto. The truck-frame is intended to be made in large part of pressedsteel.

My invention relates largely to details of the structure, which will bereadily understood from the accompanying drawings, in which- Figure 1represents a plan view; Fig. 2, a vertical elevation, partly in sectionon the line a: w of Fig. 1; Fig. 3, a section through Fig. 1 on the lineg1], and Fig. I an end elevation of part of the frame.

The truck-frame consists, generally, of the side frames A and end framesB, made of pressed flanged steel, the end frame B, entering into theside frames A, as shown in Fig. 1. The pedestals are attached in theordrnary way to projections in the side frames, as shown at C. Upon thejournal-boxes the equaliz ing-bars D rest, which are carried below thesprings E. Between the equalizing-bars D and the frame A springs E arearranged in any suitable way, as shown, being carried between upper andlower castings connected, respectively, with the side frames and theequalizing-bar.

The truck is provided with a double transom F, located on both sides ofthe bolster.

. The bolster enters the side frame, which is recessed for that purpose,while the transoms are extended and flanged at right angles and areriveted to the side frames, as shown.

The casting L is provided with a projection or pocket N, carrying alateral-motion spring P engaging with the bearing 0 attached to the sideframe. The bolster is likewise provided with sliding pieces R, commonlyknown as transom chafing-plates. A pedestal tiebar S may likewisebeemployed, of the usual construction.

Between the end frames B and transoms F safety-beams T, of pressedsteel, may be inserted and riveted, upon which the axle safetybearing Umay be attached in the ordinary way by bolting to the lower flange, theaxle safety -bearing thimbles V passing directly through both flanges ofthe safety-beam P.

The bolster M is preferably made of pressed steel, trough-shaped, andmay be strengthened at the middle by a riveted cross-piece WV.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. The pressed-steel truck for vehicles, consisting of the flanged sideframes turned inward and cut away at the center, and the end framesriveted thereto, substantially as described. 2. The combination of theside frames A A, end frames B B, and transoms FF, the side frames beingcut away for the reception of the bolster M, substantially as described.

3. The combination of the side frames A, the bolster M, carrying thepart L, serving as a bearing for the bolster-springs and for thelateral-motion spring, scribed. 4. The combination of the pressed-steelside frames, the flanged end frames entering therein, and the flangedsafety-beams attached thereto, substantially as described.

5. The combination of the side frames A, cut away for the reception ofthe bolster, and the transoms F, attached thereto and supporting theswinging hangers II and the metallic spring-plank J, substantially asdescribed.-

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
